Our experience with security certificates, as I said, began in 2005, with the security certificate five. Those returns would be made to Morocco, Syria, and Egypt. We've done quite a bit of research on each one of those individual cases. Every case where there's an issue of the non-refoulement obligation arising is assessed on a case-by-case basis. So it wouldn't matter whether all 21 of those people had been returned and none of them were tortured. What matters is, will this particular person in this particular situation, with conditions on the ground in general and specific to this person in particular, be at risk of torture? It's well established under international law that that assessment occurs on a case-by-case basis.
With respect to the five security certificate detainees that we have carefully followed, we are of the strong opinion that none of those five would be able to be returned to their home countries and be safe from torture or ill treatment--even with diplomatic assurances from those countries against torture.
